I have a 2002 F150 with the 5.4l, i changed out the spark plugs cleaned the injectors and had to replace the o-rings on injectors. Now i have an erratic idle, only from the right side, true duals. From a stop it feels and sounds like theres a missfire or bad injector, but under normal load it goes away. Truck died on me the other day, so i do a whole bunch of work that needed to be done anyways, new fuel filter, tank and pump. All lines connected back up except the fuel pressure sensor, broken, new one on the way. So the codes i have now are, P0113, P0122, P0450, P0452 and P1000. If anyone has an idea please help, tank was replaced due to an accident. Thanks inadvance!!

 

I think you left some stuff unplugged.
